Colt M4 Carbine OEM2 5.56mm 16.1" Bbl Semi-Auto Low Profile Gas Block Matte Black Rifle No Buttstock/Trigger Guard/Handguard LE6920-OEM2

The Colt M4 Carbine OEM2 Rifle is a semi-automatic, direct gas impingement rifle chambered in 5.56mm NATO, factory-configured as a stripped "builder's canvas" that lets enthusiasts fully customize their furniture right out of the box. This duty-grade foundation incorporates a 16.1-inch chrome-lined, button-rifled barrel with a 1:7" right-hand twist rate and a standard A2 flash hider, built onto mil-spec forged 7075-T6 aluminum upper and lower receivers finished in a matte black Type III hardcoat anodizing. Operating on a reliable carbine-length gas system, it comes pre-installed with a factory low-profile gas block rather than a traditional fixed A-frame tower, making it completely ready for modern free-float handguards. To reduce cost and prevent wasted factory parts, this specific SKU ships entirely devoid of a handguard, buttstock, or trigger guard, while retaining a standard single-stage trigger, an A2 pistol grip, a mil-spec receiver extension (buffer tube), and an optics-ready flat-top Picatinny rail. The rifle is compatible with all standard AR-15 / STANAG magazines.
